12 M is noon , 12 MM is midnight.   M stands for meridian.

11:59 PM is definitely in the evening, so 12:00:00 is the dividing line, being neither morning nor evening.   You can argue the other way, but it is illogical.

I avoid ambiguity by never assuming someone else has the same understanding of which date midnight is on, nor whether noon is before noon or after noon.

Hey, lets meet at noon afternoon today, and maybe noon before noon tomorrow?
